ELEVATOR FOR LOADING AND UNLOADlNG CATTLE 0N SHIPBOARD.

SPECIFICATION forming part of Letters Patent No. 227,544, dated May 11, 188C. Application filed February 27, 1880.

To all whom it may concern:

Be it known that I, HENRY P. KIEKHAM, of the city, county, and State of New York, have invented a new and Improved Elevator for Loading and Unloading Cattle on Shipboard; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making part of this specification.

This invention is in the nature of an improvement in elevators for loading and unloading cattle on shipboard; and the invention consists in an elevator for lowering and hoisting live stock into and from the decks of a vessel, constructed with uprights which may be taken apart and transported from place to place, in combination with a sliding platform, and provided with an adjustable guard, as is more particularlyT hereinafter described.

In the accompanying sheet of drawings, Figure l represents a vertical section of my a front view; Fig. 3, a horizontal section in line w x, Fig. l; and Fig. 4, a part side view, showing adjustable guard.

Similar letters of reference indicate like parts in the several figures.

This invention is more particularly adapted to loading and unloading vessels .with live stock, so that it may be accomplished not only expeditiously but humanely, and without injury or fright to the cattle or other stock that is to be shipped.

The device is also applicable for loading and unloading vessels with any other kind of cargo, since it facilitates the operation.

In the construction of my device, referring to the drawings annexed hereto, A represents two uprights, which may be of any desired dimensions. These uprights have guides a formed in their inner surfaces, and they may be supplied with braces b, or in some other way be securely fixed to bases B. The bases B have mortises o formed in them, into which mortises are received the tenons of bars G and D, which bars are held in place within the mortises by pins d. The upper ends of the uprightsAhave made on them tenons e, which tenons are received into mortises which are cut through a cross-beam, E, that spans the top ofthe uprights A, as shown in Fig. 2, and

this cross-beam is retained in its position by pins j'.

To the outer sides of the uprights A are fixed three or more eyebolts, g, and to one or the other of these eyebolts, by mea-ns of suitable hooks hor other catches, is fixed a guard, F.

Between the uprights A is placed a platform, G, so that it can be raised and lowered from the top to the bottom of the uprights A by means of a cord, i, fixed to its cross-beam k, and by means of any suitable power applied thereto, the platform being guided in its upward and downward motion by the guides a of the uprigh ts A, which are received into corresponding grooves formed into thecross-bar k and uprights l, which are fixed to the platform Gr.

Now, my device for loading and unloading cattle, &c., being' constructed substantially as above described, its opera-tion is as follows: The uprights A (for the purpose of easy transportation) are carried to the hatchway of the deck on which the cattle are to'be confined for the passage-for instance, the Steeragedeck of the steamer-at which place the uprights are set in a vertical position extending upward to thedeck next above the one on which they are placed, or thereabout. In this position they are retained by inserting the tenons of the bars C and D into the mortises o in the bases B, where they are secured by the pins d. The cross-beam E is next placed over the tenons e in the upper ends of the uprights A, so that they are received within mortises in the cross-beam and the pins f inserted to keep the cross-beam in place. Before the uprights, by the bars C and D and the cross -beam E, the platform or lift G is placed in position between the uprights, as shown in Figs. 2 and 3, the sides m of this platform or lift projecting beyond the faces ofthe uprights. When this platform is raised to its elevated or highest position between the uprights,it will then be in line with the loading-port in the side of the ship, and the cattle, 86o., enter directly fromthe loading-port to the pla orm. To prevent them from passing beyond the platform at the opposite side from that which they enter, the guard F is placed and secured to the sides of the uprights A by means of the hooks h and eyebolts g, before named. As

however, are secured together IOO soon as the required number of cattle have entered upon the platform the cord 'i is slowly slackened, and the platform with its load descends to the base of the uprights, and the cattle pass from it to their respective stalls, and the empty platform or lift is again raised for a fresh load, and so on until the loading is completed.

lo unload the vessel, substantially the same operation is gone through with, excepting, under some circumstances, the device maybe placed somewhat diiferently, the object being, in both loading and unloading, to have as far as possible the loaded platform to descend by gravity and the empty platform to be elevated by the power applied to the cord or rope t', thereby saving both time and power. This power may be applied either by a winch or in any other desirable manner.

The guard F is, as before stated, removably fixed to the sides of the upright-s A, so that it may be adjusted from one side to the other, as the loadingport of the ship may be on the starboard or port side.

When the loading or unloading is completed i the pins (l andf are withdrawn, the cross-beam E is removed, and the nprights A detached from the bars C and l), and in this detached condition the entire device may be made to i occupy a comparatively small space, so that it can be stowed aboard ship or elsewhere, if dei sired. Besides, when the parts are in this way detached the entire device is readily carried i in sections by a few men, anti put in positio'n l between decks wlth facility and without the aid of additional machinery, which would not be the case if it were otherwise constructed.

When the device is erected for operation, eyebolts a in the sides of the uprights A may have guys fixed to them extending to ringbolts in the deck or otherwise, to steady the device.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a device for loadin g and unloading live stock, the combination of a sliding platform, G, placed between uprights A, having crosspieces B permanently fixed to their lower ends, and adjustable bars G D, connected to said cross-pieces by sliding joints and uniting said cross-pieces together, and a removably-fixed beam, E, secured to the upper ends of the uprights by mortises and tenons and pins j", substantiall y as and for the purpose described.

2. In a device for loading and unloading live stock, uprights removably fixed to each other, in combination with a guard constructed to be adj usted in front of either end of a sliding platform, substantially as and for the purpose described.

3. In a device for loading and unloading live stock, al1 adjustable guard, F, in combination with eyebolts g and catches lt, substantially as and for the purpose described.
